CARTRIDGE FUSE.

Application filed May 7,

To all 'whom t may concern.'

Be it known that I, HENRY T. BUssMANN, a citizen of the United States, residing` at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Cartridge Fuses, of which the following is a clear, full, and exact description, such as will enable others skilled in the art to make and use the same.

The object of my invention is. to provide a fuse that can be easily assembled and that can be made at a low cost. These and other advantages will be more readily understood by reference to the accompanying drawings.

Fig. 1 is a longitudinal view, with casing partly broken away. Fig. 2 is a longitudinal view at right angles to that shown in Fig. 1. Fig. 3 is an end view of same. Fig t is a cross-sectional view of the fuse on the line 4&4 in Fig. 2. Fig. 5 is a cross-sectional view on the line 5 5 in Fig. 2. Fig. 6 is a perspective view of a terminal.

In the drawings, 7 is a fuse link attached to the terminal 8 by means of rivet head 9 or any other suitable means. On the terminal 8 are projections 10, preferably stamped out of the terminal itself. These projections abut against the inside of the cap 11 and hold the terminal against outward movement. Through the hole 12 in the terminal 8. a pin 13 is passed which holds the terminal against inward movement.

Various means have been used heretofore for fastening the caps to the casing, such as screws and pins. Such means are not satisfactory as such fastenings are liable to become loose and fall out. By reason of such methods as shown for holding the terminal against longitudinal movement, it is possible to make this terminal of very short length Serial No. 295,376.

and extending into the casing` for a length only sufficient to connect the fuse link thereto. This permits the use of the rivet 14, extending through holes in the cap 11 and tube l5, for fastening the cap to the tube. This rivet 14 passes through the tube in front of the inner end of the terminal.

From this it can readily be seen that I have provided a fuse of very simple design,

yet one that possesses great mechanical strength and will withstand extremely heavy overloads or short circuits.

It can also be 2. In a fuse, a casinO g, closures therefor,

terminals extending within the casing. a fuse link attached to a flatside of the flat blade terminals and a closure holding pin extending through the closure, and through the center of the casine.

3. In a fuse, a casing, a closure, a flat blade terminal extending within the casing, a fuse link attached to a iiat side of the terminal, means for preventing an outward movement of the terminal` and a pin extending through the sides of the closure in front of the inner end of the terminal and through the casing for holding the closure to the casing.
